Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure columns and beams, and in particular, it is a straightening device for steel structure columns and beams. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Steel structure columns and beams are prone to deformation during production or transportation, so they need to be straightened. However, most straightening devices can only straighten the top and bottom sides of steel structure columns and beams. This means that when straightening the sides of steel structure columns and beams, they need to be disassembled, flipped, and reinstalled. This operation is cumbersome and increases the workload of workers.

[0003] The existing Chinese patent (authorization announcement number CN222695691U) discloses a straightening device for steel structure column and beam production, which "includes a pressure platform and supporting feet evenly distributed on the lower end face of the pressure platform, and further includes: a transverse moving module, fixed at the center of the upper end face of the pressure platform, one end of which is fixed with a drive motor, which can drive the internal lead screw to rotate."

[0004] It is evident that the cited patent document suffers from the problem of inconvenience in straightening the sides of steel structure columns and beams. Utility Model Content

[0005] The purpose of this invention is to provide a straightening device for steel structure columns and beams to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straightening device for steel structure columns and beams, comprising a straightening platform, an electric push rod mounted on the top surface of the straightening platform, a lifting block connected to the output end of the electric push rod, a turntable rotatably connected to one side of the lifting block via a pin, a fixing component for fixing the steel structure columns and beams mounted on one side of the turntable, a threaded rod rotatably connected to the inner wall of the lifting block, a moving block threadedly fitted around the periphery of the threaded rod, two limiting blocks symmetrically mounted on one side of the moving block, two through slots symmetrically opened on one side of the lifting block for the two limiting blocks to pass through, four limiting slots equidistantly mounted on one side of the turntable for fitting the limiting blocks, and a base for supporting the steel structure columns and beams mounted on the top surface of the straightening platform.

[0007] Preferably, two sliding plates are symmetrically installed on the inner sidewall of the lifting block, and the moving block is slidably sleeved on the periphery of the two sliding plates.

[0008] Preferably, the fixing assembly includes a pad, a screw, and a pressure block, wherein the pad is mounted on one side of the turntable.

[0009] Preferably, the screw is rotatably connected to the top surface of the pad by a pin, and the pressure block is threaded onto the periphery of the screw.

[0010] Preferably, a slot is provided through one side of the straightening table, and a threaded shaft is rotatably connected to the inner wall of the slot via a pin.

[0011] Preferably, a transverse block is threaded around the circumference of the threaded shaft, and an inverted U-shaped movable frame is mounted on the top surface of the transverse block.

[0012] Preferably, a cylinder is installed on the top surface of the movable frame, and the piston rod of the cylinder passes through the movable frame and is connected to a pressure plate for straightening the steel structure columns and beams.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This steel structure column and beam straightening device allows the steel structure column and beam to rotate 90 degrees by rotating the turntable. By rotating the threaded rod, it provides power for the movement of the moving block, allowing the limiting block to be removed from or inserted into the limiting groove, thus fixing the position of the turntable. Compared with existing devices for straightening steel structure columns and beams, this device can flip the steel structure column and beam in a fixed state, allowing the steel structure column and beam to rotate 90 degrees, avoiding the need for disassembly and reassembly, saving both time and effort.

[0015] By setting up the fixing components, one end of the steel structure column and beam can be fixed, which facilitates subsequent straightening.

[0016] The movement of the movable frame is achieved by rotating the threaded shaft, which can be adjusted according to the position of the steel structure columns and beams that need to be straightened, and the steel structure columns and beams can be straightened. Attached Figure Description

Detailed Implementation

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The steel structure column and beam straightening device shown includes a straightening platform 1, an electric push rod 2 is installed on the top surface of the straightening platform 1, a lifting block 3 is connected to the output end of the electric push rod 2, and a turntable 4 is rotatably connected to one side of the lifting block 3 through a pin shaft. The turntable 4 can make circular motion around the pin shaft as the axis.

[0029] A fixing assembly for fixing steel structure columns and beams is installed on one side of the turntable 4. The fixing assembly includes a pad 10, a screw 11, and a pressure block 12. The pad 10 is installed on one side of the turntable 4. The screw 11 is rotatably connected to the top surface of the pad 10 via a pin. A knob is connected to the top of the screw 11. The pressure block 12 is threaded around the circumference of the screw 11. One end of the steel structure column and beam is placed on the top surface of the pad 10, and then the knob is turned to drive the screw 11 to rotate, thereby driving the pressure block 12 to move downward and press and fix the steel structure column and beam. Since the turntable 4 can make circular motion around the pin, when the turntable 4 rotates 90 degrees around the pin, it will drive the steel structure column and beam to rotate 90 degrees, thereby flipping the steel structure column and beam over, which is convenient for straightening the side of the steel structure column and beam.

[0030] Two slide rails are symmetrically installed on one side of the turntable 4. The pressure block 12 is slidably sleeved on the periphery of the two slide rails, so that the pressure block 12 will move around the periphery of the slide rails when it moves, thus limiting the movement trajectory of the pressure block 12.

[0031] A threaded rod 5 is rotatably connected to the inner wall of the lifting block 3. One end of the threaded rod 5 passes through the lifting block 3 and is connected to a handle. A moving block 6 is threaded around the circumference of the threaded rod 5. Two limiting blocks 7 are symmetrically installed on one side of the moving block 6. Two through slots 8 are symmetrically opened on one side of the lifting block 3 for the two limiting blocks 7 to pass through. Four limiting slots 9 that fit the limiting blocks 7 are equidistantly installed on one side of the turntable 4. In the initial state, the limiting blocks 7 are inside the limiting slots 9, fixing the position of the turntable 4. When it is necessary to straighten the side of the steel structure column beam, turning the handle will drive the threaded rod 5 to rotate, thereby driving the moving block 6 to move, which in turn drives the two limiting blocks 7 to move, so that the two limiting blocks 7... The steel structure column can be removed from the inside of the limiting groove 9. At this time, turntable 4 is rotated 90 degrees, which drives the steel structure column to rotate 90 degrees, flipping it over. After the turntable 4 rotates 90 degrees, the other two limiting grooves 9 will be aligned with the positions of the two limiting blocks 7. Then, turn the handle in the opposite direction, and the moving block 6 can be moved in the opposite direction through the threaded rod 5, so that the two limiting blocks 7 can move in the opposite direction and enter the other two limiting grooves 9 respectively, fixing the position of the flipped steel structure column. This straightens the side of the steel structure column, avoiding the need to disassemble and flip it over again when straightening the side of the steel structure column, reducing the workload of the workers.

[0032] Two sliding plates 20 are symmetrically installed on the inner side wall of the lifting block 3. The moving block 6 is slidably sleeved on the periphery of the two sliding plates 20. When the moving block 6 moves, it will move on the periphery of the two sliding plates 20, which can limit the movement trajectory of the moving block 6.

[0033] The top surface of the straightening platform 1 is equipped with a base 13 for supporting the steel structure columns and beams. After the steel structure columns and beams are clamped by the pads 10 and the pressure blocks 12, the electric push rod 2 is turned on, which drives the lifting block 3 to move downward, thereby moving the steel structure columns and beams downward so that the bottom surface of the steel structure columns and beams contacts the top surface of the base 13, which facilitates subsequent straightening. When flipping, the electric push rod 2 must be turned on first to move the steel structure columns and beams upward before flipping. After flipping, the electric push rod 2 is turned on again to move the steel structure columns and beams downward and contact the top surface of the base 13 again for straightening.

[0034] A slot 14 is provided through one side of the straightening table 1. A threaded shaft 15 is rotatably connected to the inner wall of the slot 14 via a pin. A motor is installed on one side of the straightening table 1. The output end of the motor passes through the straightening table 1 and is fixedly connected to one end of the threaded shaft 15. A horizontal block 16 is threaded around the periphery of the threaded shaft 15. An inverted U-shaped moving frame 17 is installed on the top surface of the horizontal block 16. A cylinder 18 is installed on the top surface of the moving frame 17. The piston rod of the cylinder 18 passes through the moving frame 17 and is connected to a pressure plate 19 for straightening the steel structure column beam. After the steel structure column beam contacts the base 13, the motor is turned on, which drives the threaded shaft 15 to rotate, thereby driving the horizontal block 16 to move, and then driving the moving frame 17 to move, so that the pressure plate 19 can move to the position where the steel structure column beam needs to be straightened. Then the cylinder 18 is turned on, which drives the pressure plate 19 to move downward to straighten the steel structure column beam.

[0035] Working principle:

[0036] The steel structure column and beam straightening device involves placing one end of the steel structure column and beam on the top surface of the pad 10, then rotating the screw 11 to move the pressure block 12 downwards, clamping and fixing the steel structure column and beam. Then, activating the electric push rod 2 moves the steel structure column and beam downwards, bringing its bottom surface into contact with the top surface of the base 13. Activating the motor then moves the moving frame 17 via the threaded shaft 15 and the cross block 16, allowing the pressure plate 19 to move to the position where the steel structure column and beam needs straightening. Activating the cylinder 18 moves the pressure plate 19 downwards, straightening the steel structure column and beam. After straightening the top and bottom sides of the steel structure column and beam, when straightening the side, first activate the electric push rod 2 to move the steel structure column and beam upwards and disengage it from the base 13, then rotate... The threaded rod 5 can move the limiting block 7 via the moving block 6, allowing the limiting block 7 to be removed from the limiting groove 9. The electric push rod 2 is then activated, causing the steel structure column beam to move upwards. The turntable 4 is then rotated 90 degrees, causing the steel structure column beam to rotate 90 degrees and flip over. After flipping, the threaded rod 5 is rotated in the opposite direction, causing the limiting block 7 to move in the opposite direction and enter another limiting groove 9, fixing the position of the flipped steel structure column beam. The electric push rod 2 is then activated, causing the steel structure column beam to move downwards and contact the top surface of the base 13. The pressure plate 19 then straightens the side of the steel structure column beam, avoiding the need for disassembly and flipping before reinstallation, thus reducing the workload of the workers.
